Wooden golf-club

WOODEN GOLF-CLUB.

To all whom t may cof/wem Be it known that I, RICHARD F. BEAMER, a citizen of the United States, and a resident of the city and county of San Francisco and State of California, have invented acertain new and useful lVooden Golf-Club, of which the following is a specification.

The invention relates to wooden golf c lubs.

An object of the invention is to provide a wooden golf club, which, with the same applied force, will drive a golf ball farther than the ordinary wooden-faced clubs.

Another object of the invention is to` pro'- vide a wooden golf club having a resilient driving face having substantially the same period of vibration as the golf ball. t Ihen a body is strained within the elastic limit, the internal stresses tend to restore the body to its original condit1on. 'W hen released from the external deformingforce, the body vibrates, and, since the restoring forces are at each stage proportional tov the distortion, the vibrations are simple harmonic vibrations of a constant period. lVhen a golf ball is struck, it is deformed and in regaining its original shape, it vibrates in simple, harmonic vibrations of a constant period. In accordance with my invention, I provide a wooden golf club having an elastic or resilient face, which when struck, vibrates in simple harmonic vibrations of the same or substantially the same constant period as the golf ball. The re@ storing stresses, therefore, of both the golf ball and the driving face, combine to drive the'golf ball from the club.

The invention possesses other advantageous features, some of which, with the foregoing, will be set forth at length in the following description, where I shall outline in full, those embodiments of my invention which I have selected for illustration in the drawings accompanying and forming part of the present specification.

Refcrring'to said drawings:

' riod of vibration as the golf ball. This sur- .face is preferably formed-of a steel plate 3,

of such resiliency and elasticity that when struck, it vibrates in time with the vibrations of the ball, so that the rebound of the plate is simultaneous with the rebound of the ball. The vplate 3 is preferably made of springsteel or saw blade steel of the necessary thickness in proportion to its area to vibrate at the required frequency. In Fig. 1, the plate 3 is substantially rectangular in shape and is provided with backwardly.

directed walls 4, which are provided on their ends with flanges 5, through which screws are passed, to secure the plate to the head. The head 6 is provided Wtih a recess 12 in its front face, and the Vplate is set in the recess with the face of the plate flush with the face of the head. This provides an open space between the plate and the rear Wall 7 of the recess so that the plate is free to vibrate in its natural period. The spaces between the side walls 4 and the sides of the recess are filled with hard rubber 8 or similar material, so that no edges or corners are presented on the face of the head.

In the construction shown in Fig. 3, the plate 3 is circular and seats in a cylindrical recess in the head, the space between the side walls and the wall of the recess being, filled with material 8.

In the construction shown in Fig. 4, the upper and lower faces ofthe head are countersunk slightly behind the recess 12 and the plate 3, instead of being provided with side walls, is provided with top and bottom walls 13 which seat in the countersunk portions. The plate is of the same width as the recess, so that it'closes the front of the recess entirely, while allowing the plate to vibrate freely, both by the flexing of the plate and the flexing of the walls.

The construction shown in Fig. 5 is simi. lar to that shown in Fig. 2, with the exception that the vibratory element, instead of being formed of one plate, is formed 'of a plurality of plates 14, producing a laminated structure.

The striking plate in all instances is spaced from the back of the recess and flush with said face, and walls extendingv backwardly from the edges of said face and secured to the bottom of the recess in-said head, the plate being spaced'trom the rear wall/of the depression so that it is free to vibrate in its natural eriod.

2. A golf club havlng a solid head with a recessed front face, a resilient striking plate having rearwardly extending flanges with Vsaid lips to secure the out-turned lips, and means passing through plate in the recess and flush with said face.

3. A golil club having a solid head with a recessed front face, a resilient striking plate having rearwardly extending anges with out-turned lips, means passing through said lips to secure the plate in the recess and flush with said face, and a filling, between said flanges and the walls of the recess, covering the securing means.

In testimony whereof, I have hereunto set my hand at San Francisco,pCa lifornia, this 15th day of May 1919.
